    Abstract S.69-79

    This chapter presents the material properties of silicon which are relevant for an understanding and modelling of the performance of typical silicon solar cell devices. It describes the mobilities, recombination rate and carrier densities that are functions of various other material properties and electrical excitation conditions in the electrical properties. The strong dependence on electrical properties and injection level can be used for contactless measurement of decisive solar cell properties. For this purpose, an accurate model for radiative recombination is important. The intrinsic recombination is the ""unavoidable"" contribution to the recombination rate related to fundamental physical mechanisms present even in perfect material quality. There are two different intrinsic recombination mechanisms: radiative and Auger recombination. The main loss contribution in common crystalline silicon solar cells is recombination via defects, mainly impurities within the crystal and surfaces. The defects essentially introduce energy states within the band‐gap, which provide a low‐energy pathway for electron‐hole pairs to recombine.

    Abstract Seed dispersal is one of the most important ecosystem functions globally. It shapes plant populations, enhances forest succession, and has multiple, indirect benefits for humans, yet it is one of the most threatened processes in plant regeneration, worldwide. Seed dispersal distances are determined by the diets, seed retention times and movements of frugivorous animals. Hence, understanding how we can most effectively describe frugivore movement and behaviour with rapidly developing animal tracking technology is key to quantifying seed dispersal. To assess the current use of animal tracking in frugivory studies and to provide a baseline for future studies, we provide a comprehensive review and synthesis on the existing primary literature of global tracking studies that monitor movement of frugivorous animals. Specifically, we identify studies that estimate dispersal distances and how they vary with body mass and environmental traits. We show that over the last two decades there has been a large increase in frugivore tracking studies that determine seed dispersal distances. However, some taxa (e.g. reptiles) and geographic locations (e.g. Africa and Central Asia) are poorly studied. Furthermore, we found that certain morphological and environmental traits can be used to predict seed dispersal distances. We demonstrate that flight ability and increased body mass both significantly increase estimated seed dispersal mean and maximum distances. Our results also suggest that protected areas have a positive effect on mean seed dispersal distances when compared to unprotected areas. We anticipate that this review will act as a reference for future frugivore tracking studies, specifically to target current taxonomic and geographic data gaps, and to further explore how seed dispersal relates to key frugivore and fruit traits.

    Abstract We determine the uncertainties on simulated efficiencies of silicon solar cells due to uncertainties of the fundamental physical models. To determine these, we refit their parameters to the underlying measurement data. Using a metamodeling and Monte Carlo simulation approach, we then deduce how these propagate to the simulated solar cell efficiency. This is evaluated for 150-μm-thick 1 Qcm p-type standard and advanced silicon passivated emitter and rear cells (PERC), as well as for an ideal silicon solar cell. When sticking to the best-known set of physical models, we determine resulting efficiency uncertainties as low as 0.06% abs for usual PERC cells and 0.1% abs for an ideal cell. In a variance-based sensitivity analysis, we find the uncertainties of the bandgap and the hole density-of-states effective mass as well as the Auger recombination in the limiting case to dominate the efficiency uncertainty. In addition to these relatively low uncertainties, larger discrepancies may arise when applying different physical models for otherwise fixed device properties. We determine comparably large efficiency discrepancies of up to 0.6% abs for the two most prominent bandgap narrowing (BGN) models, and up to 0.15% abs for the two most recent parameterizations of free carrier absorption. We also show evidence that for the specific case of a strong space charge region being present at a recombining surface, Schenk's BGN model fails to replicate experiments. Those discrepancies highlight the necessity of further research on those models. Finally, an error of up to 0.08% abs is observed by simplifying diffused regions on textured surfaces to a planar geometry.

    Abstract In March 2020 Coronavisus-19 pandemic led to significant changes in operations in healthcare in the United Kingdom with national lockdown measures imposed to help protect the vulnerable and prevent transmission. Those deemed vulnerable fall into the cohort of patients at risk of fragility fractures such as fracture neck of femur (NOF). British Orthopaedic Association released guidelines advising that NOF fractures should continue to be treated urgently.
    Aim: Our unit aimed to identify changes in NOF caseload during the national lockdown and identify if Nottingham Hip Fracture Scores (NHFS) were reliable at predicting 30-day mortality in COVID-19 positive patients.
    Methods: A retrospective observational study identifying NOF admissions over a 6-week period in 2020 during lockdown period, where demographics, NHFS, and 30-day mortality rates were compared against the same period in 2019.
    Results: There was a reduction in NOF admissions by 17.8% (55 vs 67). No significant difference in patient demographics between groups. 30-day mortality rates were not significantly increased in 2020 compared with 2019. COVID-19 positive patients had significantly increased 30-day mortality rates (54%, p = 0.001) compared to COVID-19 negative (9.1%, p = 0.395) and 2019 (6%).
    Discussion: NHFS was not reliable as a predictor for 30-day mortality in COVID-19 positive patients. Our unit reports increased mortality rates in NOF patients with covid-19 infection. This adds to the building evidence that COVID-19 is an independent predictor for mortality in NOF patients irrespective of NHFS. This should be communicated to patients who are admitted to hospital with NOF and units should continue with efforts to prevent hospital acquired COVID-19 infection.
